Description

Technical Field

[0001] The present invention relates to the field of shoe soles, and more particularly to a shoe sole. Background Art

[0002] Flat feet, also known as flatfoot deformity, is a condition in which the medial longitudinal arch of the foot is flat or absent. This condition may be caused by congenital or acquired causes that lead to incomplete function of the muscles, tendons or ligaments of the ankle, or abnormal bone structure, which cannot maintain the normal arch structure. The incidence of flat feet is related to age, gender, and weight. The incidence rate in men is higher than that in women, and the incidence rate is higher in obese children. The disease type can be divided into congenital flat feet and acquired flat feet, the latter of which is also called acquired flat feet.

[0003] Therefore, the sole is particularly important for flat feet, and there are no adjustable soles on the market for people with flat feet to try; so hereby proposes a sole that is easy to adjust for people with flat feet to use. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide a sole that can be conveniently used by people with flat feet.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a sole, characterized in that: it includes a sole, the sole is formed with a sole cavity, the sole is provided with a sealing surface for sealing the sole cavity, the sole is provided with a top block located in the sole cavity, the sole cavity is also provided with a driving member for driving the top block to move, the driving member is arranged on a side of the sole close to the heel, the sole is also provided with a fixing member for limiting the driving member, the driving member includes a driving block and a pressing protrusion, the driving block rotates in the sole cavity, one end of the driving block is connected to the top block, and the other end is connected to the pressing protrusion.

[0006] The present invention is further configured as follows: a section of the driving block facing away from the pressing protrusion is formed with a driving inclined surface, the fixing member includes a sliding fixing block, a plurality of limiting protrusions are formed on the sliding fixing block, and a clamping gap is formed between adjacent limiting protrusions, and when the driving block is clamped in the clamping gap, the top block is fixed.

[0007] The present invention is further configured such that: the sealing surface is made of a flexible material.

[0008] The present invention is further configured as follows: a limiting block for limiting the top block is protruded from the sole, two limiting blocks form a limiting gap, the limiting block is integrated with the sole, and the top block slides in the limiting gap.

[0009] The present invention is further configured as follows: an elastic cavity is formed in the pressing protrusion, a first spring is arranged in the elastic cavity, a connecting groove connected to the elastic cavity is provided on the pressing protrusion, a push rod and a pressing block are slidably provided on the sole, a pressing groove connected to the sole cavity is provided on the sole, the pressing block slides in the pressing groove and is connected to the push rod, and when the pressing block is pressed, the pressing block drives the push rod to move to the elastic cavity.

[0010] The present invention is further configured as follows: the push rod is provided with a card slot, and the pressing block is provided with a card block that slides in the card slot.

[0011] The present invention is further configured such that: a limited end is formed on the clamping block.

[0012] The present invention is further configured as follows: S1, pressing the pressing block, so that the pressing block drives the ejector rod to move to the elastic cavity; S2, then step on the driving block; S3, release the pressing block; S4, driving the four top blocks of the sliding fixed block to reset.

[0013] By adopting the above technical solution, the push rod is driven to move into the elastic cavity by the pressing block and then the push block is driven to press against the arch of the foot by stepping on the driving block, thereby ensuring the comfort of wearing the shoes.
